Perhaps not everyone knows that the skin does not sleep at all during the night, on the contrary. Numerous studies have highlighted how during the night some hormonal processes activate purification and detoxification systems in the skin. Thus, while we sleep, waste substances are released through the skin that have been accumulated during the day.

Why does this only happen at night? Perché i ritmi biologici sono circadiani ovvero avvengono in maniera non uniforme durante le ore del giorno. Because biological rhythms are circadian, that is, they occur unevenly during the hours of the day.

The process of releasing waste substances through the skin is favored by an increase in the size of the pores of the skin which at the same time are able to increase the gaseous exchange of oxygen, promoting regeneration processes.

At this point it is easy to understand that the skin, after a careful and delicate cleansing of the impurities accumulated during the day, does not need any particular cosmetic needs. Anzi l’utilizzo di creme nutrienti o con un elevato contenuto di sostanze grasse potrebbe causare una ostruzione dei pori impedendo i processi di scambio e favorendo così l’accumulo delle sostanze di scarto nella cute ingrigendola.

Indeed, the use of nourishing creams or creams with a high content of fatty substances could cause a blockage of the pores, preventing the exchange processes and thus favoring the accumulation of waste substances in the skin, making it gray.
